To all whom it may concern: a l

Be it known that 1 SAMUEL D. SHAKLEY, a resident of Pittsburg, (NorthSide,) in the county yof Allegheny and State of Pennsylvania, haveinvented a new and useful Improvement in Explosive-Engines; and'I` dohereby declare the following to be a full,

clear, and exact description thereof.

My invent-ion relates to internal combustion A engines, and has specialreference to thatform of engine known as the four cycle type.

The object of my invention is to providel a cheap, simple and efficientfour cycle engine in which the cylinders of the same may be charged andscavenged with greater eiiieiency than the present form employed.

To these ends my invention consists, generally stated, in the novelarrangement, construction and combination of parts as hereinafter morespeeiiically set forth and described and particularly pointedA out inthe claims.

To enable -others skilled in the art to which my invention appertains toconstructand use my improved internal combustion engine, I will describethe same more fully, referring to the accompanying drawings, in Which-Figure 1 is a' side elevation of the engine showing the distributer insection on tht` line :zem Fig. 2. Fig. 2 isa 'vertical sectional Fig. 1Fig. 3 is a like section on vthe line 3 3, Fig. 1. Fig. 4 is across-sectional view of the distributer on the line 4 4, Fig. 1, withthe valve at a different position. Figs. 5 and 6 are like sections onthe lines 5--5 and 6*(3, respectively, Fig. '1, with the valve atdifferent positions. Fig. 7is a longitudinal central section of anotherform of engine, showing the distributer applied As illustrated in thedrawing,"A represents my improved internal combustion engine and suchengine is provided with the cylinders 1 and 2 andmay be used inconneetion -with motor vehicles, such as automobiles, marine Wessels,etc. In each of the cylinders 1 and 2 of the r engine A theusual waterjacket 3 extends around the same, and

such cylinders havepistons 4 operating thu-ein through piston rods 5connected thereto and to the crank shaft 6 which extends through thecrank cases 7 view of the engine on the line .2f-2,'

v outer valve casing 8 and 7 of such engine. At one side of and at thelower end of the cylinders l and 2 is the distributer B, and suchdistributer Iconsists of the outer valve. casing -8, within which is theinner circular valve is connected to suitable means.

.Rotatably mounted within the casings 8 and 9 of the distributer B isthe cylindrical the cylinders 1 and 2 by any casing 9, and saiddistribute-r valve 10, and suchfvalve bears against the inner face ofthe inner casing 9 and is rota` table therein, while such valve ishollow and is provided at about its center with a wall 12 which dividessaid hollow center into the chambers 13 and 14. Extending through. valvespindle 15 which is the valve 9 is the secured firmly to said valve byits center wall 12 and such shaftis provided wit-h a spur gear or othermeans (not shown) for connecting the same to the crank shaft 6V throughachain belt or other suitable connection for revolving the same.

The valve 10 is' provided with a concave portlonl extending into thechamber 13 within said valve and' a concave portion 17 extending intothe chamber 14 in said valve and such Valve is also provided' with theopenings 18 and 18 which are diametrically opposite each other and leadinto and communicate with the chamber 13 therein, while the openings. 19and 19"in said valve lead into and communicate with the chamber 14 andthe openings'lSand 18 in said' valve are adapted to communicate atcertain periods with an through the outer valve casing 8 and the innervalve casing 9, while the openings 19 and 19 in said valve are adaptedto conimunicate at certain periods with the opening 21 which openingexten'ds through the and the inner valve casing 9 .inclosing said valve.

The outer and inner valve casings 8 and 9 are provided at-their lowerend with the openings 22 and 22 extending through the sa-me and suchopenings are directly 1n line with the' concave ortions 16 and 17respectively, in the va ve 10, while such casings are also provided attheir upper 4side with the openings 23 and 23 extending through the sameand such openings are alsoin line with the concave portions -16 and 17,respecopening 20 which extends tively, in said valve. At one end; ofthe1 valve 10 and between the end wall of the outer valve casing 8 is apassageway 24 which communicates with the chamber 13 in said valve,while another passageway is formed at the other end of the valve 10 andend wall of the outer valve casing 8 which communicates with `thechamber 14 in said valve. A f

Extending from and communicating with the crank case 7 is a pipe 26which extends upward therefrom and communicates with the passageway 24in the valve casing 8,

valve'casing, and such chamber is adapted to y or other means (notshown) in its connec` In considering communicate with the openings 23and 23 above the chambers 13 and 14, respectively.

The rear portion of the outer valve casing 8 is flared so as to formthe'passageways 30 and 30 between said valve and the inner valve casing9, and such passageyvays are adapted to communicate with the intake port32 which enters the cylinder 1 through the water jacket3, while ltheouter valve casing 8 is also ared in the saine manner to form thepassageways Bland 31, andA these passageways are adapted to communicatewith the intake vport 32 which enters the cylinder 2 through the waterjacket 3, and

the cylinders 1` and 2 are each provided with t vcylinder 2 is preciselythe same as described an exhaust port 33 and 33, respectively, and suchport in each cylinder is diametrically opposite to said intake port. Onthe upper end of each of the pistons-4 and directly in front of theintake ports 32 and 32 when saidl pistons are at their lowest positionare the deiiecting lips '34, and such lips are located near said portsand extend -vertically from said pistons.

The use and operation of my Iimproved explosive `engine is as followsr-The crank case 7 is filled with the explosive mixture, as hereinafterdescribed, and the crank case 7 is iilledwith air for scavengingl thecylinders 1 and 2 of the engine. 'The cranks on the shaft 6 are set at180 degrees apart, and the engine being of the four cycle type, aycompleteopera-tion is effected by four com- ,plete strokes of thepistons, or while the' valve shaft' 15' ismaking one completerevolution' through the medium of a Spurvgear tion with said crankshaft. the cylinder 1 and the crank case 7 attachedthereto the piston 4is shown at its downward position and said cylinder .has just been.cleansed of the exploded mixture, and is now ready for a new charge. Atthis time the valve 10 is at a position as shown in Fig. 2, and theconcave portion "16 on said valve will allow the mixture, coming fromthe crank case 7, through the pipe 2@ and chamber 27, to pass from theopening 22 into the passageway 30, and thence through the `port 32 intosaid cylinder.

i The piston now rises by the action of' thepis-` ton 4 in the cylinder2 through the medium of the crank shaft 6, and'when the piston 4 inthe'cylinder 1 has reached its raised position in said cylinder themixture therein is exploded in the usual manner and said' piston isforced downward, thus opening the ports 32 and 33 in said cylinder.During this operation of the piston the 4valve 10 has been revolvedone-half a revolutionV and the air, which has been compressed in thecrank case 7 byV the downward stroke of the piston 4 in the cylinder 2,rushes-up through the pipe 28 and through the passageway 25, the chamber29, andthe opening 23 in the valve casings 8 and 9. The. valve will nowbe in a position such as is .shown at F ig. 3, and the air will passthrough the passageway 30 and thev port 32 and strike the deiiectinglips 34, which will, tendfto throw the air through the 'uppermost partsof the cylinder 1 and such air will then be exhausted through theexhaust port 33 and into an exhaust manifold 35 on the side of saidcylinder, while the piston 4 in the-same will then be forced upward andwill reverse and start downward and thus compress the gas or explosivemixture contained inl the crank case 7.

The operation of the piston 4 within the 105' except that such operationis one hundred and eighty degrees behind the operation of the piston inthe cylinder 1, so that when the one cylinder is receiving its charge ofmixture the other cylinder is being scavenged of the exploded mixturecontained therein.

l/Vhen the concave portion 16 of the valve 10 is at a position such asshown in Fig. 4 or Fig. 5, and when the piston 4 is ascending in thecylinder 1, the opening 18 or 18 in the valve 10, which openings arediametricallyw opposite each other, will be over the `opening 20 in thevalve casings 8 and 9 andthe'mixture will be vdrawn into such openingsby this action and admitted to the crank case 7 throughthe chamber 13 inthe valve'lO and the passageway 24 and lpipe 26 leading to said crankcase, and in like manner air wiil be drawn into the crank case 7 wheneitherA the opening 19 or 19 in said valve is communicating with theopening 21 in the valve casings 8 and 9, and such air will pass into`the chamber 14 and through the passageway 25 andthe pipe 28 leading .tosaid crank case, and when the piston in icoV ' pressed air from thecrank oase 7" fao the communication of said openings will have been cutofll so that the air or mixture in the crank case Will then becompressed by the dovvnvvard stroke of the piston. It will` th-us beseen-that .when the mixed explosive charge from the crank case 7' ispassing into the cylinder l, the comis passing into the cylinder 2 andexpelling the exhaust gases from the same intothe manifold 35,

and in like mannerwhen the .mixed explosive charge from the crank case 7is passing into the cylinder 2 the cylinder 1 isv being cleansed by thecompressed air from the crank case 7 as before described."

With the use of my improved internal combustionengine, such engine .mustin all cases be of the four cycle type and must have two or morecylinders and suc'h lcylinders must be connected in pairs so that thealternating rocess of admitting 'explosive mixture and) accomplished,and it will be obvious that with my type of engine all springs andpuppet Valves in the combustion chamber willbe entirely eliminated sothat much inconvenience and annoyance `caused by such parts getting outlof repair 'will be done away with.

In the .regular four cycle type of engine employed in general use atthis time a large amount of the ignited or exploded mixture remains inthe combustion chamber after the exhausting operation so that when thenew explosive mixture is admitted into such chamber it unites with thesaid remaining exploded mixture and thus renders the same exceedinglyless efficient, While in the use of my improved engine all this troublewill be avoided by the automatic scavenging of the cylinder withcompressed air to relieve the same of all exploded gases.

In the case of heavy duty engines of either the verticalor horizontaltype, the latter of which is shown in Fig. '7, Where there is a chamber36 at theend of each piston opposite to Where the combustion takes placeand formed by the back Wall of such cylinder and said piston the pipe 26Will communicate With the chamber 36 of the cylinder 1 and crank case 7,and the compression of the mixture Will be accomplished in such chamber,While the pipe 28 Will communicate Wit-h the chamber 36 of the cylinder2 and crank case 7, and the compressionof the air Will be accomplishedin sucli last named chamber.

-It Will be evident that rthe distributer of myim roved enginemay beoperated by means rom the crank shaft other than those,l described andthat various modifications and changes in the design and construction ofthe engine, the distributer and 'its operation may be resortedto,without departing from air for scavenging may be` chambers for thespirit of the invention or sacrificing any of its advantages.
